Symptoms

Elevated blood pressure doesn't cause symptoms. The only way to detect it is to keep track of your blood pressure readings. Have your blood pressure checked at each doctor's visit — or check it at home with a home blood pressure monitoring device.

When to see a doctor

All people age 3 and older should have their blood pressure checked by a doctor at least once a year. You might need more-frequent readings if you have elevated blood pressure or other risk factors for cardiovascular disease.
